Every runtime cost in this calculator comes from actual operating data, cross-referenced with the Holmberg racing cost tracker. The Rush SR runs about $150/hour all-in: fuel, tires, brakes, oil, chain, suspension, and amortized rebuilds. Use the “Compare to” selector to see how that stacks up against SRF3, Spec Miata, or GT4.

This calculator shows car costs only. No travel, no entry fees. Those costs are roughly the same no matter what car you race. Runtime is where the Rush SR stands alone.

Owned: you already have a Rush SR. The calculator shows runtime costs only.

Buying: includes the car ($49,995), competition spec package ($9,974), and safety equipment on top of season costs. When comparing, the competitor’s purchase price is shown side-by-side.

Renting: teams rent Rush SRs for $3,500–$8,000/weekend depending on distance from dealer, level of support, competition level, and number of days/races. Rental generally includes all consumables and runtime.

The incident buffer ($2,000–$5,000) is optional but recommended: racing is racing.

This calculator doesn’t account for buying a trailer, a tow vehicle, or tools. It doesn’t include the cost of time off work or the conversations with your spouse. For the full picture, read the complete cost breakdown.
